For activists Twitter privacy dynamics can be dangerous and seem to force 
activist to compromise their own safety. To try and explore alternatives I'm
using two twitter accounts:
 public @nathanafain. does not follow back. says lots.
 private @cyphunk. follows people. retweets @nathanafain.

Twitter account metadata and network graph are accessible and open for anyone to
harvest and analyse. Unless the account is set to private. But private accounts
can can no longer interact with anyone not already in their network. They can no
longer take part in public conversations, a central feature of Twitter. This may
cause many to sacrifice their metadata. That trade-off could be dangerous.

After building a workshop for activists that teaches techniques for exposing
anonymous adversaries it became more apparent how valuable the metadata of
social media accounts is toward this goal. Critically the longer a target is
digitally active the higher the probability of metadata from old personas
revealing information about their anonymous activity today.

Recently I've watched acquaintances and comrades in Berlin get harassed by
authorities for their anti-racist work. In some cases they have been deported.
They have been deported for comments that are falsely assumed to indicate
association. Indicators of weak association are exactly what network graphs are
great for. I expect such graphs are already used privately for targeting. I
worry in the future they might be used publicly as grounds for punishment. 

So I'm trying to understand how activists that are at greater risk than me can 
respond to these privacy concerns. The method of split private/public accounts 
probably has many issues. It is certainly not very user-friendly or accessible. 
But this setup is an attempt to explore some of these issues.
